  • Oncogenic viruses are the known etiologic agents in 15% – 20% of all human cancers. Their impact on global health is signifi cant. The fi rst recognition that cancer can be caused by a virus dates back to observations of Rous sarcoma virus in chickens almost 100 years ago. However, it was not until the 1970s that the mechanistic basis for retroviral transformation became clearer. That era was marked by the discovery of many viral oncogenes and counterpart cellular proto - oncogenes.

  • This comprehensive volume covers the major viral, bacterial and fungal diseases in fi n- and shellfi shes. It completes the three-volume series on fi sh diseases and disorders; Volume I (published in 1995) is on parasitic diseases in fi n- and shellfi shes while Volume II (published in 1998) deals with non-infectious disorders in fi nfi sh. Reviews in the three volumes are written by international authorities that are actively working in the area or have contributed greatly to our understanding of specifi c piscine diseases or disorders.

  • Even though human oncogenic viruses belong to different virus families and utilize diverse strategies to contribute to cancer development, they share many common features. One key feature is their ability to infect, but not kill, their host cell. In contrast to many other viruses that cause disease, oncogenic viruses have the tendency to establish long-term persistent in- fections. Consequently, they have evolved strategies for evading the host immune response, which would otherwise clear the virus during these persistent infections.

  • The Kaposi’s sarcoma-associated herpesvirus protein SOX (shut off and exonuclease) and its Epstein–Barr virus homolog, BGLF5, are active during the early lytic phase and belong to the alkaline nuclease family. Both proteins have been shown to be bifunctional, being responsible for DNA maturation as well as host shutoff at the mRNA level.

  • We planned the first edition of this book on a ‘need to know’ basis, its primary object being to provide students and medical and dental practitioners with the knowledge essential for an informed approach to the prevention and treatment of viral infections. We aimed also at supplying just enough basic virology to underpin the more practical aspects—clinical manifestations, epidemiology, pathogenesis, immune responses, and so forth. And not least, we tried our best to make the text as readable as is possible, given the highly technical nature of some of the material.

  • Presenilins are required for the function of c-secretase: a multiprotein complex implicated in the development of Alzheimer’s disease (AD). We analyzed expression of the presenilin 1 (PS1) gene. We show that ERM recognizes avian erythroblastosis virus E26 oncogene homolog (Ets) motifs on the PS1 promoter located at)10, +90, +129 and +165, and activates PS1 transcription with promoter fragments containing or not the)10 Ets site.
